The Void

From LSWiki

   an aether [compass, compass:up, compass:down, u, d]

   This is a void, a vacuum of empty aether.  To the north, south, east, and
west, as well as above and below is emptiness.  The area is permeated by a
thick, intense field of emptiness.  The pull of gravity is completely absent. 
The area is reasonably well-lit.  
   Dreamy and Khing are here.  
   Obvious exits lead in all compass directions and their upward and downward
variations, as well as up and down.

   You peer at your surroundings.
   You determine that you are at the coordinates -4, -2, 6 in Void.

   You concentrate on the planar fabric.
   You reach outward with your psychic senses and determine that you are on
the amalgamal plane of Void.

This is an airless expanse accessible through the Exoma as an aether.

It is 20x20x20 in size, and loops back upon itself in all directions. If you wish to explore it, you'll need to have wingless flight to move around, and either internal or no respiration to survive, as there is no air here to breathe. There is an Exoma portal that wanders and will very slowly pull you towards it, but unlikely to be fast enough to save the hapless. Note that this can mess with speedruns and idle meditation, as you will be forcibly moved when the pulls tick.

A strange brilliant chaotic glow surrounds your body as you are forcibly pulled to the east against your will.

As each pull takes 3 to 5 (or 8) minutes to occur, relying on them to find the exit can easily take over an hour.

Here you can find various Glomerates' nihilsphaerae as well as a mix of loamots, elementals, and amalgamals.

Elemental and amalgamal types found here thus far include:

* Air
* Cold
* Darkness
* Entropy
* Shadow
* Void

The proper name for this place is actually "Void", or "the amalgamal plane of Void", as shown by 'determine location' and 'concentrate on the planar fabric'. Therefore, this is the correct article. It can be expected most if not all Elemental, Amalgamal, Cardinal, Axiomatic (and so forth) Planes follow more or less this basic structure (entirely their element, perhaps no solid ground at all), but it depends.
